This is a late reply but I encountered this issue and I have solved it with the following steps:

SVG icons of the default theme (adwaita) needs to be copyed to a share directory relative to the bin directory bin../share/icons/Adwaita/scalable/* also bin../share/icons/Adwaita/icon-theme.cache and bin../share/icons/Adwaita/index.theme

After several test, it appears that the following files are also required:

lib/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-svg.dll
lib/gdk-pixbuf-2.0/2.10.0/loaders/loaders.cache

The first line of this loaders.cache file also needs to be edited to "../lib/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-svg.dll"

The file tree looks like this:

bin/gtkapplication.exe
bin/*.dll
share/loader.cache
share/glib-2.0/gschemas.compiled
share/icons/Adwaita/scalable/*
share/icons/Adwaita/icon-theme.cache
share/icons/Adwaita/index.theme
lib/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-svg.dll
lib/gdk-pixbuf-2.0/2.10.0/loaders/loaders.cache
